Post back details after cart transaction to database

Need script sp that after user completes process at mals eccommerce it's remote call functions will send variables to a script where script will add contact information if it doesn't already exist (in infusionsoft based on email address). And add a tag based on product purchased in either case. Need an GUI admin so I can add product names and tags for script to look for so I can use it in the future. Logic: If User buys product X, script send variables from cart to script via remote call as outlined at mal's ecommerce...based on product purchased - if product is listed in list add associated tag to infusionsoft for the user record. Create user record if it doesn't exist (whether product is in list or not) and add tag if product purchased is in list.) [login to view URL] Email any questions.
